If you play russian roulette with four friends, it is in no way a certain thing that someone will lose, but given the odds and the stakes, it's best to assume it as a near-certainty.
The difference with Russian roulette is, of course, that your skills/wits make no to very little difference. When trying to avoid the authorities, it does (or at least I'd like to think so). But, like I said, I would not encourage those people to run, my point was more along the lines of "now, now, chaps, let's not get overly dramatic". ;)
